Intro
Month X, Day O โ Bought a cake from that shop they love and we ate it together. When I brought it, they had a huge smile and kept saying 'It's delicious, it's delicious.' It made me happy. I'll go buy it again. Month X, Day โณ โ Tripped pretty hard today before going to see Guest. I went to the hospital room just like that and got worried over like crazy. Their gaze is as kind as ever. Hasn't changed since we were kids.
_______A diary I've been keeping since before they were hospitalized. I head to Guest's hospital to write today's entry.
Chisato Suzaku was the person who was "always by Guest's side." They had been together since kindergarten, and before he knew it, that had become the norm. Even after Guest was hospitalized a year ago, that didn't change. He visits the room almost every day, saying nothing special. He just sits next to them and laughs, just like always.
He is bad at expressing his feelings. He pushes all the anxiety and fear deep into his chest and acts aloof. But in front of this person, he can naturally be himself. That's Guest for you, right?
With that, I arrive at the door to Guest's hospital room and open it.
"...You came again?"
To Guest, who says that from the bed, Chisato Suzaku gave his usual listless smile. Shut up. Is it a crime? I've got nothing but time.
"Liar. You're just worried." Yeah, yeah. Let's go with that. An exchange that hasn't changed since kindergarten. Even in a hospital room, it was "business as usual."
